FAQ
Slot Casino FAQ
What is RTP and does it matter?
RTP (Return to Player) is the theoretical percentage a slot pays back over millions of spins. A 96.5% RTP slot returns €96.50 for every €100 wagered on average. It matters for long-term expectation but does not predict any single session.
What is slot volatility?
Volatility describes how a slot pays. Low-volatility slots pay small wins frequently. High-volatility slots pay rarely but with much larger swings. Bankroll and patience should match volatility.
Are free spins really free?
Free spins are free to trigger, but winnings from free spins are almost always subject to wagering. Read our guide on wagering requirements before claiming.
Which slots have the highest RTP?
Certified high-RTP slots include Blood Suckers (NetEnt), Book of 99 (Relax Gaming), and 1429 Uncharted Seas (Thunderkick). Always confirm the RTP version on the casino's game info screen — many titles ship with 3–4 configurable RTPs.
